MACHINERY OR APPARATUS FOR WINDING YARNS R THREADS.

SPECIFICATION forming part of Letters Patent No. 494,723, dated April 4, 1893.

Application filed March 24,1891. Serial No. 386,263. (No model.) Patented in England May 4,1889, No. 7,439, and in Germany November 8,1889,N0.54,888.

T0 on whom it may concern.-

Be it known that I, FERDINAND Ross- KOTHEN, engineer, of Aachen, Prussia, in the German Empire, have invented certain new and useful Improvements in Machinery or Apparatus for Winding Yarns or Threads into Cops or Pirns, (for which British Letters Patent numbered 7,439 and dated May 4, 1889, and a German patent numbered 54,888 and dated November 8, 1889,-have been granted unto me,) of which the following is a specification.

When winding yarn or thread into the shape of a cop or pirn the thread-guide by means of which the yarn or thread is guided While being wound requires to have two movements in relation to the spindle, one an oscillating movement and the other a movement in a direction parallel or nearly parallel to the axis of the pirn or cop being wound. The two motions together serve to cause the yarn or thread to be so distributed as to form a cop or pirn.

The above mentioned movements of the thread-guide in relation to the spindle, can be obtained either by imparting to the thread-guide in addition to its oscillating movement an additional movement which moves it gradually from the base to the point of the cop or pirn or by imparting to the thread-guide an oscillating movement only, and causing the spindle to move in the direction of its axis so as to carry the base of the cop or pirn away from the thread-guide. The motions first referred to are those generally adopted in forminga cop or pirn on the mule and the latter motions are those generally employed in winding or forming a cop or pirn in winding machines. Machines for winding yarn or thread into the form of cops or pirns have as hitherto constructed been considerably defective, among other defects being that those machines in which both the spindles and the thread-guides are moved, could not be run at a high speed because the spindles on which the cops or pirns are wound cannot be firmly supported and in those machines in which the spindles are not moved in the direction of their axes the spindles are usually not independent of each other or in those cases in which they are independent of each other the independence ofsuch spindle is only obtained by the employment of complicated arrangements of apparatus.

By means of my invention hereinafter described I am enabled to form cops or pirns upon spindles which have no movement other than rotation. 1

In the accompanying drawings Figure 1 is a diagram illustrative of the principle upon which the apparatus constructed according to my invention operates; Fig. 2 a cross section of such portion of a machine as is requisite to show the application of my invention to winding yarns or threads on to independent spindles. Figs. 3 and 4 illustrate a method of causing the fulcrum of the thread guide lever to be moved by means of a spiral cam, and also a method of arresting the rotation ofthe spindleandthe movement ofthefulcrum of the thread-guide lever when the yarn or thread breaks or becomes absent. Fi s. 5 and 6 are respectively an elevation and plgn illustrative of a method in which the fulcrum of the thread guide lever is caused to be moved by the winding of the yarn or thread upon the spindle, and Figs. 7 and 8 are respectively a side elevation and a plan showing a slightly varied arrangement of the apparatus by means of which the Winding of the yarn or thread upon the spindle is caused to move the fulcrum of the thread-guide lever.

According to my invention I employ as a thread-guide a lever, which is capable of being turned upon a pivot to which I impart a motion which gradually carries it in the direction of the axis of the spindle. end of the lever I form or secure a thread guide. The other end of the said lever is acted upon by suitable mechanism so that an oscillating motion will be imparted to the lever by which each layer of the yarn or thread being wound is distributed upon the pirn 0r cop. The movement of the pivot on which the lever is mounted, causes the layers of the yarn or thread to be so arranged as to form a cop or pirn.

The pivot before referred to can be caused to move in the direction of the axis of the spindle by any convenient means. According to one arrangement I mount the said On one pivot upon a lever so placed that each layer of yarn or thread wound upon the cop or pirn will cause the said lever to be turned upon its fulcrum, and carry the thread-guide away from the base of the cop or pirn. During the above described motion of the thread-guide the part at which such threadguide receives its motion will continue to OS- cillate in the same or nearly the same path. Instead of the lever which carries the pivot of the thread-guide being directly acted upon by the yarn or thread being wound upon the cop or pirn the said lever may be provided with a cup or roller or rollers, against which the yarn or thread may act, such cup, or roller or rollers being connected to or mounted upon a tube capable of being slid upon the lever aforesaid.

In place of employing the yarn or thread wound upon the cop or pirn to move the lever before mentioned, I in some cases employ a cam, incline or screw, to move such lever, and in those cases in which it is desired to doif at one time all the cops or pirns wound simultaneously in a machine, the pivots of all the thread-guides are moved simultaneously but, if as I prefer, it be desired that each spindle shall be independent of the others, each pivot must be moved independently of the others.

In some cases I mount the pivot on which is mounted the thread-guide, on a lever which rests upon a spiral cam which is slowly rotated by means of a ratchet wheel or by other suitable means. The rotation of the cam will cause the pivot on which the thread-guide is mounted to be raised. By varying the rate at which the cam is rotated, cops or pirns of different diameters may be formed. By altering the length of the lever resting upon the spiral cam, a greater or less amount of movement may be caused to be imparted to the said lever and thus the diameter of the cops or pirns may be varied without the rate of rotation of the cam being varied.

In those cases in which I cause the yarn or thread wound upon the cop or pirn to raise a lever, cup or roller or rollers, I prefer to employ a stop motion to stop the rotation of a spindle when the yarn or thread being wound upon such spindle becomes broken or absent, and thereby prevent injury to the yarn or thread being caused by the last layer of yarn or thread continuing to rub against the lever, cup or roller or rollers.

In those cases in which the lever on which the pivot of the thread-guide is mounted is moved by means of a spiral cam, screw, or incline, or other suitable means, I prefer to cause the movement of such spiral cam, screw, or incline or other suitable means to be stopped when the spindle is stopped, so that thin places are prevented from being formed in the cops or pirns.

I have above described each of the levers or thread-guides as being mounted upon a lever moved as the building of the cop or pirn proceeds, either by'the yarn or thread wound upon the spindle in conjunction with which such leveror thread-guide is used, or by means of a cam or incline or other suitable apparatus, but I would have it understood that each of such levers or threadguides may be mounted and arranged to be moved in any suitable manner so that while guiding the yarn or thread to be wound upon the spindle such lever or thread-guide may be moved away from the base of the cop or pirn as the building of such cop or pirn proceeds.

In the accompanying drawings Figure 1 is a diagram showing the movements of the thread-guide which are necessary to be made in relation to the spindle in order that yarn or thread may be wound upon a spindle in the form of a cop. In addition to an oscillating movement such thread-guide must also have a slow progressive motion, which progressive motion causes the yarn or thread to be wound on the spindle in layers.

In Fig. 1 Aindicates the part of the threadguide lever A which guides the thread. The thread-guide lever A is joined at A and A to the rods B and C respectively. If a short oscillating motion be imparted to the rod 0 in the direction of the length of such rod 0 so that the point A is moved to A the part A of the thread-guide lever A will be moved to A and so guide the yarn or thread that a conical layer of yarn or thread will be coiled upon the spindle D. If the rod B is gradually moved in the direction indicated by the arrow E so that the pivot A shall be moved into the position indicated by dotted lines A and without the amount or direction of the motion of the rod 0 being altered the part A of the yarn or threadguide A which guides the yarn while being wound upon the spindle D will be moved along the path indicated by the dotted lines A** A***.

By the longitudinal movement of the rod B in the direction indicated by the arrow E the path of the part A is gradually moved from the base to the point of the cop. of an oscillatory motion being imparted to the rod C and gradual longitudinal motion being imparted to the rod B an oscillating motion be imparted to the rod B and the rod C be caused to be gradually advanced in the direction opposite to that indicated by the arrow E the movement of the guide Wire A will be similar to that above described.

The arrangement above described in reference to Fig.1 is only applicable in those cases in which a number of cops or pirns are being formed or built simultaneously, that is, in which the whole number of such cops or pirns are begun simultaneously and finished simultaneously.

According to another arrangement of my invention each cop or pirn may be commenced, wound, and completed independently of the other cops or irns which are being wound. One moth of carrying If instead this arrangement of my invention into effect is shown in Fig. 2. The thread-guided is capable of being oscillated upon a fulcrum b. c is a shaft which is caused to oscillate by any convenient means. Secured to the shaft 0 is an arm 0. Jointed to the arm 0' is one end of aconnectingrodd jointed at its other end to one end of the thread guide a. The fulcrum b of the thread-guide a is carried by a rod e upon which are formed screw threads which take into screw threads formed in the boss of a wheel f which is carried by and free to revolve in a rail g and is prevented by such rail 9 from being moved in the direction of the length of the rod 6. The rotation of the wheel f will cause the rod e to be moved longitudinally thereby moving the fulcrum b of the thread-guide a from the point F to the point F. A rod e and wheel 1'' for raising the fulcrum b of the thread-guide w is applied to each thread-guide aso that each spindle is rendered independent of the others.

Figs. 3 and 4 show an arrangement in which the movement of the fulcrumb of the threadguide a is caused by means of a spiral cam h. The spiral cam 71. is fast with the ratchet wheel j and is loose upon the shaft is. On the circumference of the spiral cam h rests a lever Z carried by and capable of being turned upon a bar m secured to any convenient part of the machine. Fast upon the shaft is is an arm is carried by and jointed upon which is a pawl n the tooth of which passes into the teeth of the ratchet wheel j.

The shaft is is caused to oscillate by any suitable means. Ooiled around the boss of the ratchet wheel j is a cord 0 by which is suspended a weight 19 such weightp tending to turn the ratchet wheel in the direction indicated by the arrow G, q is a catch which prevents the ratchet wheel j from being turned by the weight p in the direction indicated by the arrow G. To the lever Z is secured a rod 0 from the upper end of which projects a stud b which forms the fulcrum upon which the thread-guide (1 turns. The thread-guide a, is jointed at one end a* to one end of a connecting rod (1 the lower end of which is jointed to an arm 0 fast upon a shaft 0 which is caused to be oscillated by any suitable means. The oscillation of the shaft is will by means of the pawl it cause the cam h to be slowly turned in the direction opposite to that indicated by the arrow G. Such turning of the cam h will cause the lever Z to be gradually raised, thereby gradually raising the part a** of the thread-guide a which guides the yarn or thread while being wound upon the spindle t and thereby cause the yarn to be wound upon the spindle t in the form of a cop. In the lever Z, I form a slot 1 through which and through the rod r passes a bolt by means of which the rod 7' is secured to the lever Z. By securing the lower end of the rod r in the slot Z so that such lower end of the rod r is somore quickly the cops are formed of a less diameter. 1

In Figs. 5 and 6 is shown in elevation and plan an arrangement in which the fulcrum b of the thread-guide a is' raised by the yarn or thread as it is wound upon the spindle t. Upon the lever 11 which has its fulcrum at o is a cone or cup 10. When this cone or cup to is put on the cop which is inthe course of being wound the axes of the spindle t cone or cup to are in one straight line. In order that this may be I mount upon the lever v and free to be slid thereon a tube v provided with a stud '0 upon which and free to be turned thereon is a collar w to which the cone or cup to is secured. The threadguide lever a, is carried upon the lever o by means of a fulcrum b. Mounted upon and free to slide upon the end (1*, of the threadguide lever a is a tubeacprovided with astud m which passes into a hole formed in an arm 0' fast upon a shaft 0 to which an oscillating motion is imparted by any convenient means. The oscillation of the shaft 0 will by means of the arm 0' stud as and tube a: impart an oscillating motion to the thread-guide lever a. In the side of the cone or cup to next to the thread-guide a I form a slot to through which the yarn or thread passes from the threadguide a to the cop being wound upon the spindle 6. Each layer of yarnor thread which is wound upon the spindle t by means of the thread-guidea lifts the cone or cup to and along with it the lever 12 and the fulcrum b carried thereby. The lever 11 has its fulcrum at Q) and when the thread-guide a is midway between the extremes of its oscillations upon the stud m the axis of the stud ac and the fulcrum '1) of the lever 12 are in the same straight line, consequently the path of the part a** of the thread-guide a by which the yarn or thread is guided upon the cop always remains opposite the slot @11 of the cone or cup to. To facilitate the piecing of the yarn or thread the cone or cup to lever "u and thread-guide a can be turned upward until the lever 12 rests against and is supported by a rail .2 secured to the framework of the ma chine, as shown by the dotted lines H. The rail 2 also supports by means of a bracket .2" the stud 0. The turning of the parts above mentioned as indicated by the dotted lines may be accomplished without stopping or interrupting the oscillating motion of the arm 0' for, as the tube wis free to be slid along the thread-guide a and can also turn the stud w round, it is free to follow the motion of the arm 0 although the lever 12, cone or cup w and thread-guide a are turned into the raised position shown by the dotted lines H.

In some cases I mount the cone or cup to upon the lever v as shown in Figs. 7 and 8, Fig. 8 being a plan of that which is shown in elevation in Fig. 7. Upon the lever 12, a portion only of which is shown I mount so that it is capable of being slid thereon a tube v to one end of which is jointed the cone or cup w.

I am fully aware that before the date of my application for a patent, in machines or apparatus for winding yarn or thread into cops or pirns spindles have been employed which have no movement other than rotation but, in such cases where the yarn or thread-guides used in conjunction with such spindles were influenced by the yarn or thread wound upon the spindles, the entire threadguide which was generally a bell-crank lever was moved from one position to another but according .to my invention the apparatus whichl employonly turns upon the fulcrum 1).

hen the yarn or thread is employed to move the fulcrum Z) upon which the threadguide lever a is carried such moving of the fulcrum b ceases simultaneously with the breakage of the yarn or thread being wound, and as long as no more layers of yarn or thread are wound upon the cop or pirn the cone or cup and with it the fulcrum of the thread-guide remain stationary. In those arrangements in which the fulcrum of the thread-guide is not moved by the yarn or thread wound upon the cop or pirn but by special mechanism it is desirable that the progressive motion of the fulcrum should cease when the thread breaks; for if this is not the case, a gap or hollow will be formed in the body of the cop or pirn being wound corresponding with the time which has elapsed between the breaking and the piecing of the yarn or thread.

In Figs. 3 and 4E previously referred to, is shown a stop motion by means of which I cause both the revolution of the spindle and the progressive motion of the thread-guide to be stopped when a yarn or thread breaks. For this purpose I provide the spindle t with two warves 2, 2, the upper warve 2 being fast upon the spindle t and the lower warve 2 being loose upon the said spindle t. 3 is a lever carried and free to be turned upon a stud 4: secured to the spindle rail 5 or any other convenient part of the machine. Projecting from the lever 3 are two pegs 6 between which passes the band 7 by means of which the spindle t is driven. Secured to the spindle rail 5 or other convenient part of the machine is a stud 8 upon which and free to be turned thereon is a lever 8 formed at one end with a curl or eye 8" and at the otherend with a tooth 8 which at times hooks upon a tooth formed upon the lever 3. The levers 3, 8 are shown in the position which they occupy when yarn or thread is being wound upon the spindle t. The yarn or thread being wound upon the spindle 25 passes through the eye or curl S and thence over the guide pulley 9 and thence through the guide of the thread guide lever Q. So long as the tension of the yarn or thread maintains the lever 8 in the position in which it is shown, the band 7 will pass around the warve 2 and drive the spindle 25, but, upon the yarn or thread becoming broken or absent, the end 8 of the lever 8 will be caused by its weight to descend into the position shown by dottod lines J and thereby carry the tooth 8 clear of the tooth upon the lever 3 which will then by its weight be caused to descend into the position in which it is indicated by the dotted lines M. The descent of the lever B will by means of the pegs 6 carry the band 7 from the warve 2 to the warve 2 and thus stop the spindle if. The descent of the lever 3 will cause it to arrive against a projectingpart n on the pawl n and thus raise the pawl 77. clear of the teeth of the ratchet wheel j and consequently prevent motion from being imparted to the ratchet wheel j. It may be here mentioned that this stop motion constitutes no part of the present invention.

I have above in most cases described and shown my invention applied to regulate the building of the cop or pirn upon each individual spindle, but if desired such apparatus can be employed to govern the building of the yarn or thread upon a number of spindles simultaneously.

In all the examples of my invention illustrated the thread guide is caused to have an invariable length of movement for directing the layers of thread on the cop and a progressive movement in one direction for the building of the cop without the end a of the thread guide lever where the oscillation is imparted to it taking part in the progressive movement of the fulcrum of said lever or of thethread guide, the point of connection between the said end (11* and the arm 0 or rod cl which transmits motion to it having an unvarying range of movement between two fixed positions.
